Holyhead, August 9th,—Evening.
I have had a bad night, a high fever, bad weather, and rough roads. The latter misery I incurred by choosing to visit the celebrated ‘Paris mines’ in the Isle of Anglesea. This island is the complete reverse of Wales; almost entirely flat—no trees, not even a thicket or hedge—only field after field. The copper-mines on the coast are, however, interesting. My arrival having been announced by Colonel H——, I was received with firing of cannon, which resounded wildly from the caves beneath. I collected several beautiful specimens of the splendid and many-coloured ore: the lumps are broken small, thrown into heaps, and set on fire like alum ore, and these heaps left to burn for nine months: the smoke is in part caught, and forms sulphur. It is curious to the uninitiated, that during this nine months’ burning, which expels all the sulphur by the force of the chemical affinity created by the fire, the pure copper, which had before been distributed over the whole mass, is concentrated, and forms a little compact lump in the middle, like a kernel in a nut-shell. After the burning, the copper, like alum again, is washed; and the water used for the purpose is caught in little pools: the deposit in these, contains from twenty-five to forty per cent of copper; and the remaining water is still so strongly impregnated, that an iron key held in it, in a few seconds assumes a brilliant copper colour.
The ore is then repeatedly smelted, and at last refined; after which it is formed into square blocks, of a hundred pounds weight, for sale; or pressed by mills into sheets for sheathing vessels. A singular circumstance is observable at the founding, which is a pretty sight. The whole mass flows into a sand-bed or matrix, divided into eight or ten compartments, like an eating-trough for several animals: the divisions do not quite reach the height of the exterior edge; so that the liquid copper, which flows in at one end, as soon as the plug is drawn out must fill the first compartment before it reaches the second, and so on. Now the strange thing is, that all the pure copper which was contained in the furnace remains in this first compartment,—the others are filled with slag, which is only used for making roads. The reason is this;—the copper ore contains a portion of iron, which is magnetically affected: this holds the copper together, and forces it to flow out first. Now as they know pretty accurately, by experience, what proportion of pure copper any given mass of ore will contain, the size of these compartments is regulated so as exactly to contain it. The manager, a clever man, who spoke half Welsh half English, told me that he had first invented this manner of founding, which spared much trouble, and that he had taken out a patent for it. The advantages which arise from it are obvious; since without these divisions or compartments, the copper, even if it flowed out first, must afterwards have spread itself over the whole mass. The Russians, who in matters of trade and manufacture suffer nothing to pass neglected, soon sent a traveller hither to make himself master of the process. It was not in the slighest degree concealed from him;—indeed it is but justice to say that the masters of all commercial and manufacturing establishments in England are generally very liberal.
While I was yet standing by the furnace, an officer made his appearance, and in the name of the brother of Colonel H——, who is likewise a colonel, and commands a Hussar regiment in this neighbourhood, invited me to dine and spend the night. I was, however, too tired and unwell to venture on the exploit of a mess-dinner in England; where, in the provinces at least, the wine is dealt out in right old English measure. I wished too to sail by the packet of to-night; and therefore gratefully declined the invitation, and took the road to Holyhead, where I arrived at ten o’clock.
My usual ill luck at sea did not permit me to sail,—the night was so rough that the packet went off without passengers. I staid behind, not very unwillingly, to take another day’s rest in a comfortable inn.
August 10th.
Ill and languid as I am, an excursion to the newly built light-house, four miles from hence, has given me extraordinary pleasure. Although the Island of Anglesea appears very flat, its picturesque craggy rocks rise on the western shore to a very considerable height above the sea. On one of these rocks, which stands out to sea, abrupt and isolated, is placed the light-house. This indescribably wild cliff is not only perpendicular—the summit actually projects several hundred feet beyond the line of the base; so that it appears rather as if blasted by powder, than the work of nature. Treading on a thick carpet of yellow dwarf broom and crimson heath, you reach the edge of the precipice: you then descend four or five hundred steps, roughly hewn in the rock, till you come to a little bridge suspended on ropes; across this, holding by its net-work sides, you swing, as it were, over the chasm which separates this rock from the main land. Thousands of sea-mews wheeled around us, uttering their ceaseless melancholy wail to the storm. The young ones were just fledged, and the parent birds took advantage of the rough weather to exercise them. Nothing could be more graceful and interesting than these flying lessons. The young were easily distinguished by their gray colour and their yet unsteady flight; while the old ones hung poised sometimes for the space of a minute without moving a wing, as if upborne motionless by the storm. The young ones often rested in the crevices of the rocks, but were soon driven out to fresh exertions by their inexorable parents.
The light-house is exactly like that which I have described to you at Flamborough Head, on the eastern coast of England, only without the revolving lights. The neatness of the oil-vessels, and the wonderful brightness of the mirror-like reflectors were here, as there, most admirable. I remarked an ingenious sort of rough-weather window, which may be opened in the hardest gale, without trouble or danger of breaking; and a vertical stone staircase, like a saw, which saves much room. But I cannot make you understand either without a drawing.
Dublin, Aug. 11th.
A more unprosperous voyage it is hardly possible to have. I was ten hours tossed about, sick to death. The heat, the disgusting smell of the steam-boiler, the universal sickness,—it was a frightful night—a picture of human misery, worthy of Carl of Carlsberg. In a longer voyage one gets hardened, and many new sources of pleasure compensate for privations; but short voyages, which show only the dark side of the picture, are my greatest aversion. Thank God it’s over, and I once more feel firm ground under me; though I sometimes think Ireland rocks a little.
